Bake API - bpy.ops.object.bake() New operator that can calls a bake function to the current render engine when available. This commit provides no feature for the users, but allows external engines to be accessed by the operator and be integrated with the baking api. The API itself is simple. Blender sends a populated array of BakePixels to the renderer, and gets back an array of floats with the result. The Blender Internal (and multires) system is still running independent, but we eventually will pipe it through the API as well. Cycles baking will come next as a separated commit Python Operator: ---------------- The operator can be called with some arguments, or a user interface can be created for it. In that case the arguments can be ommited and the interface can expose the settings from bpy.context.scene.render.bake bpy.ops.object.bake(type='COMBINED', filepath="", width=512, height=512, margin=16, use_selected_to_active=False, cage_extrusion=0, cage="", normal_space='TANGENT', normal_r='POS_X', normal_g='POS_Y', normal_b='POS_Z', save_mode='INTERNAL', use_clear=False, use_split_materials=False, use_automatic_name=False) Note: external save mode is currently disabled. Supported Features: ------------------ * Margin - Baked result is extended this many pixels beyond the border of each UV "island," to soften seams in the texture. * Selected to Active - bake shading on the surface of selected object to the active object. The rays are cast from the lowpoly object inwards towards the highpoly object. If the highpoly object is not entirely involved by the lowpoly object, you can tweak the rays start point with Cage Extrusion. For even more control of the cage you can use a Cage object. * Cage Extrusion - distance to use for the inward ray cast when using selected to active * Custom Cage - object to use as cage (instead of the lowpoly object). * Normal swizzle - change the axis that gets mapped to RGB * Normal space - save as tangent or object normal spaces Supported Passes: ----------------- Any pass that is supported by Blender renderlayer system. Though it's up to the external engine to provide a valid enum with its supported passes. Normal passes get a special treatment since we post-process them to converted and "swizzled" Development Notes for External Engines: --------------------------------------- (read them in bake_api.c) * For a complete implementation example look at the Cycles Bake commit (next).

Fix Cycles baking active/cage Basically what we address here is to make sure the active object and the cage are not interferring with the baking result (e.g., when baking Combined). To do so, we take advantage of the fact that we create our own depsgraph for baking. So now we can change the cowed objects, instead of the original ones. Note: There is still a way to get a crash. If you try to bake from selected to active when is_cage, but with no cage object, we get an assert: ``` BLI_assert failed: //source/blender/blenkernel/intern/DerivedMesh.c mesh_calc_modifiers(), at (((Mesh *)ob->data)->id.tag & LIB_TAG_COPIED_ON_WRITE_EVAL_RESULT) == 0 ``` We can bypass this by passing ob_low instead of ob_low_eval to bake_mesh_new_from_object on object_bake_api.c:847 . But then the edge split modifier change will take no effect.

Bake API - bpy.ops.object.bake() New operator that can calls a bake function to the current render engine when available.

Bake-API: new approach for cage There is a new option to select whether you want to use cage or not. When not using cage the results will be more similar with Blender Internal, where the inwards rays (trying to hit the highpoly objects) don't always come from smooth normals. So if the active object has sharp edges and an EdgeSplit modifier you get bad corners. This is useful, however, to bake to planes without the need of adding extra loops around the edges. When cage is "on" the user can decide on setting a cage extrusion or to pick a Custom Cage object. The cage extrusion option works in a duplicated copy of the active object with EdgeSplit modifiers removed to inforce smooth normals. The custom cage option takes an object with the same number of faces as the active object (and the same face ordering). The custom cage now controls the direction and the origin of the rays casted to the highpoly objects. The direction is a ray from the point in the cage mesh to the equivalent point to the base mesh. That means the face normals are entirely ignored when using a cage object. For developers: When using an object cage the ray is calculated from the cage mesh to the base mesh. It uses the barycentric coordinate from the base mesh UV, so we expect both meshes to have the same primitive ids (which won't be the case if the cage gets edited in a destructive way). That fixes T40023 (giving the expected result when 'use_cage' is false). Thanks for Andy Davies (metalliandy) for the consulting with normal baking workflow and extensive testing. His 'stress-test' file will be added later to our svn tests folder. (The file itself is not public yet since he still has to add testing notes to it). Many thanks for the reviewers.
